On the Sun Fire 15K server, the DR driver consists of a platform-independent
driver (dr) and a platform-specific module (drmach).
The domain configuration server (DCS) accepts DR requests from the domain
configuration agent (DCA) that runs on the Sun Fire 15K system controller.
After the DCS accepts a DR request, it uses the libcfgadm(3LIB)
interface to initiate the DR operation. After the operation is performed,
the results are returned to the DCA. For more information about the DCS, refer
to the dcs(1M) man page
and the Sun Fire 15K Dynamic Reconfiguration User Guide.
For more information about the DCA, refer to the System
Management Services (SMS) Dynamic Reconfiguration User Guide.
The DR driver creates physical attachment points for system board slots
that take one of the following forms:
Where x represents the expander number (0
to 17) for a particular board.
plugin creates dynamic attachment points. These attachment points refer to
components on system boards, including CPUs, memory, or I/O devices. Refer
to the cfgadm_sbd(1M)
man page for more details.
